I had the same problem ever since the first day I got my Super. My video card happens to be 3090 too.
For a couple months I had to put stickers to block 3 tracking cameras, leaving only one working, and it fixed the problem for me. I just need basic tracking without the controllers so it was fine with me.
Then the new update ( I believe it’s 14.3.1) update the firmware in the Super and finally fixed this stutter problem. Stickers were removed and the tracking is working fine.
By the way, maybe you should turn off the vertical sync in Nvidia’s control panel. It helps too.
